Hey, That appears to be calcium deficiency. Usually caused by low ph in soil. It wont be readily absorbed below 6.2. I dont see any in your feed schedule, if you're not supplying any, that will it. Cheers,

Check your PH make sure it is above 6.2. Also add Cal Mag to your nutrient feed. Also try not to over water.

Stains on the plant
Hey guys, first of all, thank you for taking the time to read this. I started growing my first canopy and since I am little excited, I started before everything I ordered arrived. For that reason, I am still using the soil I used while planting the seed. Did I fuck up already?

Pest Control/Prevention before flower?
Noticed this on one of my leaves, I already had to deal with the mite situation with my cucumber. Are they the cause of this? or another pest possibly? What methods other then neem oil and my homemade spray can help me fend them off even more?

One of my 3 plants is significantly smaller than the other 2. Her leaves are multiple colours. She was late to shed her shell so I peeled it off myself. She is still steadily growing however I have been unable to diagnose her. The photos of her are labelled "sick one"

Spotting issue consistent in all my grows. Have always thought Cal deficient but more Cal never fixes the issue. PH always checked with 2 PH pens 6.2-6.8.
Always pops up around the same time in flower.. week 4/5. Brown irregular spots and occasional curling down on the fan leaves. The only things I have consistently used in all the grows is the LED light, RO water, and CALiMAGic. Switched to dry organics but now its back. N toxic?

In week 12 of the diary I show the continued issue with yellowing and loss of leaves. One G13 plant has nearly lost all its leaves. I think I have a pest issue, see week 11 diary picture of the pot with lots of white tiny things crawling. Could this be root aphids?

Does this look like leaf miner damage? There are small tracks on most of the older leaves similar to the picture.

Please tell me why the veins of the leaves are so yellow!?
Please tell me why the veins of the leaves are so yellow!? what could it be? zinc block or cal-mag shortage ? pH all the time was 6.3-6.5, EC first was 0.7 today when I saw the yellowness on the leaves I lowered the EC to 0.5

spots on leaves
There are some spots on some leaves. I don't see spider mites, aphids or thrips. It has been very hot last week, around 35 degrees celcius Does anyone have an idea what it could be? Should I cut the leaves or is it okay??
